I noticed my iPhone X running dog-slow and the 5GE icon showing up about the same time. I'm on 12.2. I sat side by side with my wife's iPhone 6 and ran Okla's Speedtest. The iPhone 6 with LTE got 12 down and 3 up. 5GE got 7 down and less than 1 (.62) up. Is it an issue with iPhone X or 12.2 or 5GE??
